Extending / Bundled Extensions /
Activation

Once your Bundle can be autoloaded, then one more step is needed to enable Bolt
to load them.

To activate a Bundle, you need to add an extensions key to either your
.bolt.yml or .bolt.php file in the root of your project, with the values
being the Bundles you want Bolt to load. If you don't have one of these files
already then starting by creating an empty .bolt.yml is the easiest way to
get started.
